Procedure for obtaining Powders Of Metal Oxides from the desnitracion nitricas Solutions and equipment for it desnitracion

摘要

This is a procedure for the extraction of metal oxide powders of ceramic compounds from a denitrification solution, which includes the determination of accuracy and bringing them to an appropriate lethal Z level, denitrification solution, calcification, pressing and sintering. 2. Control the pressure in the vessel, and carry out Denitration Process within the pressure range lower than atmospheric pressure, especially between 720 and 400mm mercury. The other is unauthorized deprivation to develop the stages of deprivation procedures,It includes a denitration reactor (9) located in the microwave oven 88,with an outlet conduit connected to a condenser (10) associated with a condensate collector (11) and a vacuum pump (13) placed at the outlet. The equipment contains a vacuum gauge (14) and a valve for pressure control (15). The application is the obtention of metallic oxides in the form of ceramic grade powder for the manufacture of nuclear combustible materials or ceramic elements, such as varistors, supercoductors and sensors, with an average particle size of less than 0.7 microns.
